  • embodiments of the inventive concepts disclosed herein may be directed to a system and a method configured to present a view of an AMM and taxi routing guidance content.
  • Some embodiments include use of a taxi route (e.g., an instructed taxi route or a predicted taxi route) along with a current aircraft position along the taxi route to determine when to provide an "approaching runway” annunciation to the crew.
  • a taxi route e.g., an instructed taxi route or a predicted taxi route
  • Some embodiments may provide a more robust functionality of the approaching runway feature functionality to alert the crew to nearing runways in more instances than just a straight-line approach. Informing the crew of approaching runways reduces the risk of unintentionally entering runways.
  • the AMM may include a depiction of an aircraft 104.
  • the AMM may utilize a multi-function window (MFW) map window to provide a more detailed view of airport map data (e.g., at ranges below 2 NM).
  • MFW multi-function window
  • flight crews will utilize the AMM 102 map ranges (e.g., less than 2 NM) to provide a detailed representation of an airport during ground operations.
  • the view 102 of the AMM has an exemplary map range.
  • the AMM may provide a given level of detail within the map based on a selected map range (e.g., automatically declutters or clutters map details based on the selected map range).
  • One of the features provided by the AMM 102 is the ability to determine when the aircraft's 104 ownship track is projected to intersect with a boundary(ies) of a runway and provide an annunciation (e.g., an approaching runway annunciation) to the crew to this effect.
  • airport surface database(s) may include airport surface data, which includes information of an airport surface.
  • airport surface databases may include the Airport Surface Database (ASDB) and/or the Airport Surface Routing Network
  • ASRN is a data set containing "nodes” identifying the location and various other characteristics of navigable airport surface features (such as taxiway-taxiway intersections, runway-taxiway intersections, parking stands, etc.) and "edges" providing information how nodes are interconnected from a navigation standpoint. This information can be used to construct possible paths or routes from one location to another at a given airport.
  • an aircraft's ownship track projection is a straight line extending some distance from a nose of such aircraft, and the aircraft's ownship track projection does not cover all possible scenarios that would correlate with real-world situations, such as situations involving parallel taxiways and/or curved taxiways leading to a runway.
  • Some embodiments may include using a taxi route (e.g., an instructed taxi route or a predicted taxi route), aircraft state data, and airport surface data to generate taxi routing guidance content.
  • a taxi route e.g., an instructed taxi route or a predicted taxi route
  • aircraft state data e.g., an instructed taxi route or a predicted taxi route
  • airport surface data e.g., an airport surface data
  • Some embodiments may include using an instructed (e.g., an intended) taxi route that has been provided by ground control entered into the aircraft's computing device(s), and combining the instructed taxi route with airport surface data (e.g., ASRN data).
  • the instructed taxi route may be entered via any suitable means, such as via a datalink and/or by interfacing with a user interface system (e.g., 304, as shown in FIG. 3 ) (e.g., via voice, eye tracking, keyboard entry, mouse, and/or trackpad). Combining the instructed taxi route with the information provided in airport surface data may allow for taxi routing guidance.
  • At least one processor may generate and provide a crew taxi routing guidance content, which may include at least one approaching runway annunciation.
  • the approaching runway annunciation may indicate that the aircraft 104 is approaching a runway along the instructed taxi route, which is accurate even if the instructed taxi route traverses and/or is proximate to parallel taxiways, curves, etc.
  • Some embodiments may include using a predicted taxi route. For example, in the absence of direct tum-by-turn taxi routing information to determine approaching runway annunciations, a predicted taxi route may be used as part of a more desirable solution. For example, by using airport surface data (e.g., from ASDB and/or ASRN) with various ownship data parameters (e.g., position, direction, speed, braking, aircraft size, aircraft weight, aircraft category, and/or typical/common taxi routes taken by these types of aircraft), some embodiments may be capable of predicting a most likely taxi route the aircraft 104 will or should take. With the most likely taxi route determined, the system may initiate an approaching runway alert to be presented to the crew at appropriate times.
  • airport surface data e.g., from ASDB and/or ASRN
  • ownship data parameters e.g., position, direction, speed, braking, aircraft size, aircraft weight, aircraft category, and/or typical/common taxi routes taken by these types of aircraft
  • the system can determine a proximate node(s) in the ASRN (e.g., where the aircraft 104 is relative to ASRN data points). For example, by using this information, the system can determine the predicted taxi route at least in part by determining all possible valid maneuvers emanating from that node, by traversing the ASRN.
  • determining all possible valid maneuvers emanating from that node may include: (a) following each edge from each node, while computing a metric for each route (e.g., a total distance, or a total estimated time based upon other data such as maneuvering speeds or distances); (b) avoiding edges which cause the route to traverse the same node a second time (e.g., to avoid circular routes); and/or (c) constraining each node by only following edges within bounds of the aircraft's 104 orientation and maneuvering capabilities (e.g. if the aircraft's 104 heading is North, then a South edge can be disregarded).
  • a metric for each route e.g., a total distance, or a total estimated time based upon other data such as maneuvering speeds or distances
  • avoiding edges which cause the route to traverse the same node a second time e.g., to avoid circular routes
  • constraining each node by only following edges within bounds of the aircraft's 104 orientation and maneuvering capabilities (e.
  • Processing for a given possible taxi route may be complete when the system determines whether the given possible taxi route will or will not trigger an approaching runway alert (e.g., if the cumulative route length exceeds a defined threshold distance for alerting, or the cumulative time-to-intercept computed along the route exceeds a defined threshold duration, an alert would not be triggered based upon this particular route).
  • an alert would be triggered, notifying the pilot of the approaching runway.
  • determining a predicted taxi route may include: comparing possible taxi routes to a list of typically used taxi routes; and if the possible taxi route is not among this list, a shorter distance or time-to-intercept could be used.
  • determining a predicted taxi route may include the use of artificial intelligence, neural network, and/or machine learning operations (e.g., determining the probability of a given possible taxi route being taken and/or using a weighting factor to dynamically adjust the distance and/or time-to-intercept thresholds).
  • Al, neural networks, or other machine learning algorithms may be employed to refine the relationships between an arbitrary set of input parameters and a set of outputs. Relevant data may also be logged and correlated to provide context for later process steps.
  • AI and machine learning in general, and neural networks in particular employ processing layers organized in a feed forward architecture where neurons (nodes) only receive inputs from the previous layer and deliver outputs only to the following layer, or a recurrent architecture, or some combination thereof.
  • Each layer defines an activation function, comprised of neuron propagation functions, such as a Hyperbolic tangent function, a linear output function, and/or a logistic function, or some combination thereof.
  • AI and machine learning in general, and neural networks in particular, utilize supervised learning conducted during the design phase to establish weighting factors and activation functions for each node.
  • supervised training a designer may adjust one or more input biases or synaptic weights of the nodes in one or more processing layers of the neural network according to a loss function that defines an expected performance.
  • the designer may utilize certain training data sets, categorized as selection data sets, to choose a predictive model for use by the neural networks.
  • the neural network adjusts one or more input biases or synaptic weights of the nodes in one or more processing layers according to an algorithm.
  • the training algorithm may comprise a first component to minimize disparity with approaches labeled "stable” and a second component to prevent close approximation with approaches labeled "unstable.”
  • maximizing disparity with unstable approaches may be undesirable until the neural network has been sufficiently trained or designed so as to define constraints of normal operation within which both stable and unstable approaches are conceivable.
  • training data sets may be categorized based on a defined level of stability or instability, and provided in ascending order of convergence such that the disparities between stable and unstable approaches diminish during training and necessary adjustments presumably become smaller over time according to first and second order deviations of the corresponding loss function.
  • the loss function may define error according to mean square, root mean square, normalized square, a weighted square, or some combination thereof, where the gradient of the loss function may be calculated via backpropagation.
  • the AMM shows the aircraft 104, a taxi route 202 (e.g., an instructed taxi route or a predicted taxi route), an intersection 204, and runway boundaries 206A, 206B.
  • aircraft 104 is headed approximately north on the taxi route 202, which includes curves.
  • intersection 204 e.g., a taxiway intersection
  • current systems may trigger an approaching runway annunciation for the runway boundary 206A (e.g., identifying that RWY 06 / 24 is being approached along the current track or direction of travel with the boundary at dotted line "A"); however, runway boundary 206A is not along the taxi route 202, and therefore, such an unneeded approaching runway annunciation may distract the flight crew.
  • the taxi route 202 shows that the approaching runway indication should be triggered when within an appropriate predefined range of runway boundary 206B (e.g., to cross RWY 01 / 19) while following the taxi route 202, regardless of current track or direction of travel at the shown current position of the aircraft 104.
